Patients were diagnosed with IGE based on scalp EEG and presentation to a hospital after first general tonic-clonic convulsion. It is unclear though possible that they experienced staring spells that would be consistent with absence epilepsy prior to this age of diagnosis though they did experience absence seizures after onset age that were captured on video EEG.
